What is the big deal
The idea started in 2013 when I started to compete in Benchrest target shooting. I noticed the real good shooters had a bunch of windflags out on the range. After talking to many of them I realized the amount of experience, time and effort needed in order to read these. Not to mention everyone had their own unique take on the same thing.
Being slightly impatient on the road at being better at hitting what I am aiming at in the wind, I conceptualized an idea that would bypass most of the math/ calibration issues, and turbulence factors. It resulted in the initial, now discontinued, Windmeister T1. It worked good and still does, but it was big, a little cumbersome to setup/carry. So last year I decided to make a Jr version, and that is what you currently looking at, officially released at EBR.
The biggest advantage of this type of device vs. a flag type, is that it doesn't really matter how strong the wind is. As long as it is within a range reacted to by the device. This is tuned by the size of the paddle. Most of them leave the shop set at a range from 0-10mph. The medium sized paddle, or 25 sq/in. We developed an Android app that you can download for free, to help in setting up the device other than factory setting.

The beauty of this system is that you only need to shoot a couple of times in a windy condition where the red dot is somewhat steady. Example, the red dot hovering around the #1, you take a couple shot at a sighter and lets say you are at 24X on your scope. And it shows 2 mill holdover. You don not need to do conversion of wind speeds, mill dots, or magnification not being at 10X.
Simple fact is, if you had 2 Mills where the Windmeister showed the number 1, you know that when the device shows the number 2, it's twice the holdover, i.e. 4 mills. Or conversely, say the Windmeister is showing somewhere between half and 1, you know it'll be 1mill favoring 1.5mill.
Here is a video showing this in practice.
Paddle & Wind direction
This process is true no matter what distance, or what caliber you are shooting. Placement would typically be about 1/3 distance from the shooting bench to your target. The device is engineered to show zero holdover in pure tail/head wind. And will increase the the holdover as the wind direction goes toward full, or 90 degree to the flightpath. The paddle itself is pivoting, and offset from the rotation center so it will align itself to face the wind direction.
By reducing the paddle size, you essentially increase the range, and by making it bigger you decrease the range, but in return you make it more sensitive. Some LV shooters choose to have both a medium sized and a Large size paddle, so they can swap them out if needed.
High-powered rifles at long range doesn't care so much about light wind, sub 2mph, so they opt for the medium and small paddle.
